ABSTRACT:
A safety closure and container which is childproof, but can be readily opened by an adult. The container has a cylindrical neck defining the opening into the container. Threads are formed in the container neck and at least one locking lug projects from the container neck below the threaded portion. The closure has an internally threaded cylindrical flange adapted to be threaded on the container neck, and a second cylindrical flange having a larger diameter than the threaded flange. At least one resiliently mounted lug engagement finger projects inwardly from the second cylindrical flange and is adapted to abut the locking lug when the closure is in place over the container neck to prevent the unthreading of the closure from the neck. A lever associated with the resiliently mounted finger is depressed to displace the finger out of abutment with the locking lug thereby allowing the closure to be unthreaded from the container neck.
